Jelet exam 2021 etech , jelet exam will held in month of august

Spread the love

Jelet is the exam for diploma student’s who wants to do further studies btech after diploma. JELET  exam  for 2021  would be more competitive so concentrate and give more focus in E.TECH because it will carry lost of marks in the jelet exam, so we suggest you to get trips and tricks  from that institution. and exam is on your door  ,they have announced the month but didn’t mentioned about the date ,the reason is pandemic. But the board of council announced that it will held in the last week of august.


 In this article we are discussing about the ETech  and in the last we have quiz for you guys related to the topic. and in the next article we  will come up with the  many other subject and many other topic related to your  jelet exam 2021.

Network Elements

  • Active & Passive Elements:

If any elements absorb, dissipate, waste, convert electrical energy it is called as passive element. Example… Resistor, Inductor, Capacitor.

If any elements energize, deliver, give out, drive the electrical energy it is called as active element. Example. BJT, MOSFET.

  • Network Technologies:

Node : It is a point of interconnection or junction between two or more components.

Branch : It is an elemental connection between two nodes.

Mesh:  A mesh is a close path which should not have any further closed path in it.

Loop : All possible close path.

  • Ohm’s law:

At constant temperature and for uniform cross section of conductor. V=IR,

Short circuit & open circuit

Voltage across terminals of a short circuit is always zero, regardless of the value of current which could be any value. (R = 0)

The current through an open circuit is always zero, regardless of voltage across the terminals which could be any value. ( R =∞)

  • Kirchhoff’s current law(KCL):

It states that any instant the algebraic sum of current leaving any junction (or node) in a network is zero.

In other words, current entering a node is equal to current leaving the node.

Mathematical application:

∑ Iin=∑ Iout I1+I2=I3+I4


  • Kirchoff’s voltage law (KVL):

It states that any instant the algebraic sum of the voltage around any closed path (or loop) within a network is zero. In other words, the sum of voltage drops is equal to sum of voltage rises.


∑Vdrop =∑Vrise

Here we collect some quiz for that institution  and it will help you to grow your knowledge in E.TECH

  10. Hi this is somewhat of off topic but I was wondering if blogs use WYSIWYG
    editors or if you have to manually code with HTML.
    I’m starting a blog soon but have no coding know-how so I wanted to get guidance from someone with experience.
    Any help would be greatly appreciated!

  11. I intended to write you one tiny word to thank you so much as before for your personal great thoughts you have shared above. It was surprisingly open-handed of people like you to make without restraint all a number of people would’ve supplied as an electronic book to help with making some profit on their own, precisely given that you could have tried it in the event you decided. Those ideas also acted like the fantastic way to comprehend someone else have a similar dreams similar to mine to understand significantly more with reference to this problem. I know there are some more enjoyable situations up front for folks who scan your blog.
